Ingredient temperature stabilization apparatus for post-mix beverage dispensing machines

Claim 1

In a post-mix beverage dispensing machine: a cabinet having a chamber therein; means for refrigerating said chamber; means within said chamber for utilizing a liquid ingredient in preparing a beverage to be dispensed; an ingredient container within said chamber; generally horizontally extending partition means within said container dividing the interior of said container into separated upper and lower zones, said partition means being provided with an opening placing the bottom of said upper zone in restricted liquid communication with the top of said lower zone; means for permitting introduction from time to time of supply-replenishing quantities of a liquid beverage ingredient at substantially ambient temperature into said upper zone of said container, said introduction means including an open-top overflow cup within said upper zone of said container adjacent the top thereof, into which cup said quantities of said ingredient may be initially introduced for relatively gentle overflow therefrom into the remainder of said upper zone for minimizing agitation in connection with intermixing of said newly introduced quantities with quantities of cooler ingredient already within said upper zone; means coupled with said ingredient utilization means and communicating with said lower zone adjacent the bottom thereof for removing from said lower zone amounts of said ingredient as required for the preparation of beverages to be dispensed, whereby said quantities of said ingredient initially introduced into said cup at ambient temperature are gently delivered to said container and are cooled during storage and migration thereof from said upper zone to said lower zone as said amounts of already cooled ingredient are removed as required from said lower zone.
